Hi, We use several static libraries in our project as our run-time. To add debug info for a class X I just do: g++ X.cpp -I../include -c -g -Wall -o X.o ar rsu ../lib1.a X.o That worked OK with any class from our library but at the moment I have some issues with class X. I can't see its members in a debugger gdb. gdb says that class X is <incomplete type>. I tried to do 'ptype X' in gdb and got the following: No symbol "X" in current context. I looked into it more, did objdump for X.o file and saw that there is no address near the symbol which looks like my class X. I tried 3 different versions of g++ (4.3.x, 4.4.x, 4.5.x), tried following parameters for gcc: -g3, -g2 -O0, -ggdb, -gstubs+. But nothing helped. My class X also doesn't use anonymous unions. Does anyone have an idea what is wrong with g++ or with my class X? Thanks in advance. -- Yours sincerely, Vyacheslav V. Yurkov
